Description

Technical Field

[0001] This utility model belongs to the field of thermosetting powder coating processing technology, specifically relating to a quantitative feeding device for processing environmentally friendly thermosetting powder coatings. Background Technology

[0002] In the production of thermosetting powder coatings, multiple materials need to be mixed. When adding materials to the mixing device, the accuracy of the raw material feeding directly affects the stability of product quality. Currently, quantitative screw feeders are used to achieve quantitative feeding of materials. With the increase of the conveying speed and instantaneous flow rate of the quantitative screw feeder, the technical requirements for the accuracy of the quantitative mechanism and the stability of the equipment have increased significantly. Quantitative screw feeders that can achieve precise quantitative feeding at high speeds have high technical costs, and the equipment production and procurement costs are also high. Quantitative screw feeders that can achieve precise quantitative feeding at low speeds are low in cost, but the feeding efficiency is low. In large-scale industrial processing, the amount of material added is large, which affects production efficiency. There is a lack of low-cost devices that can achieve high-speed feeding. Utility Model Content

Several of the small-volume quantitative feeding mechanisms are respectively installed above the raw material feeding hoppers. A limit ring is fixedly connected to the outer wall of the raw material feeding hopper. The annular weighing device is installed below the limit ring.

The small-volume quantitative feeding mechanism is installed on the side wall of the side support plate. An outer support ring is provided below the several annular support plates.

[0005] Each of the annular support plates has two support rods fixedly connected to its bottom end.

[0018] Please see Figures 1-4This utility model provides the following technical solution: a quantitative feeding device for processing environmentally friendly thermosetting powder coatings, including several raw material feeding hoppers 1, several control valves 11, several small-volume quantitative feeding mechanisms 2, and several annular weighing devices 3. Several small-volume quantitative feeding mechanisms 2 are respectively installed above the raw material feeding hoppers 1. Limiting rings 12 are fixedly connected to the outer wall of the raw material feeding hoppers 1. The annular weighing devices 3 are installed below the limiting rings 12. Annular support plates 4 are fixedly connected to the bottom of several annular weighing devices 3. A side support plate 41 is fixedly connected to one side of the annular support plate 4. The small-volume quantitative feeding mechanisms 2 are installed on the side wall of the side support plate 41. An outer support ring 5 is provided below several annular support plates 4.

[0019] In this implementation scheme: the outer support ring 5 and the inner support ring 51 are installed above the mixing tank. Multiple raw material feeding hoppers 1 are evenly distributed above the mixing tank. Multiple small-volume quantitative feeding mechanisms 2 are installed above the multiple raw material feeding hoppers 1. When adding materials, bagged finished raw materials are directly added to the raw material feeding hopper 1 after removing the packaging. The raw materials are added until they approach the required weight. The weighing result of the annular weighing device 3 is observed. When the added weight is close to the required weight, the coarse addition is stopped, and the small-volume quantitative feeding mechanism 2 adds a small amount of raw materials to the raw material feeding hopper 1 according to the weight difference. Until the weight of the raw material in the raw material feeding hopper 1 is the same as the actual requirement, accurate weighing is not required during the filling of most of the raw material. This allows for faster addition of materials to the raw material feeding hopper 1, saving time. When the small-volume quantitative feeding mechanism 2 quantitatively conveys materials, the material conveying speed requirement is low. Achieving accurate feeding at low speed is less costly than achieving accurate feeding at high speed. It has a simple structure, small size, and low material cost. The production or procurement costs are low, enabling rapid and accurate addition of large volumes of raw materials in a low-cost manner.

[0020] In one implementation scheme, bagged raw materials are directly used for material addition. During the processing of environmentally friendly thermosetting powder coatings, 80 kg of resin needs to be added in the raw material mixing stage. Using a bag weight of 25 kg, after adding three bags of resin to the raw material feeding hopper 1, a portion of the fourth bag is added to the raw material feeding hopper 1, so that the weight of resin in the raw material feeding hopper 1 approaches 80 kg, such as about 78 kg. Then, the controller 6 controls the small-volume quantitative feeding mechanism 2 to replenish the resin raw material in the raw material feeding hopper 1 according to the weight measurement data of the ring weigher 3, so that the resin raw material in the raw material feeding hopper 1 is replenished to 80 kg.

[0021] In another implementation, materials are added directly from the silo to the raw material feeding hopper 1. During the processing of environmentally friendly thermosetting powder coatings, 80 kg of resin needs to be added during the raw material mixing stage. The silo pipeline delivers resin raw materials to the raw material feeding hopper 1, and the raw material is delivered to the raw material feeding hopper 1 to about 78 kg. Then, the controller 6 controls the small-volume quantitative feeding mechanism 2 to replenish the resin raw materials to the raw material feeding hopper 1 according to the weight measurement data of the ring weigher 3, and replenishes the resin raw materials in the raw material feeding hopper 1 to 80 kg.

[0022] With the installation of multiple raw material feeding hoppers 1, small-volume quantitative feeding mechanism 2, and ring weighing device 3 in conjunction with the outer support ring 5, various raw materials can be fed. This can reduce the cost of production equipment and increase the material feeding speed. The raw material feeding hopper 1 can be used as a pre-filling tank. When the mixing tank is mixing the previous batch of materials, various raw materials are pre-filled in multiple raw material feeding hoppers 1. After the mixed materials in the mixing tank are discharged, the control valve 11 can be opened directly to mix the next batch of materials, reducing the downtime of the mixing tank during the material addition process and improving the material mixing efficiency.

[0023] Each of the several annular support plates 4 has two support rods 42 fixedly connected to its bottom end; the support rods 42 can support the annular support plates 4.

[0024] The outer support ring 5 has an inner support ring 51 inside it. The support rod 42 located in the inner ring is fixedly connected to the top of the outer support ring 5, and the support rod 42 located in the inner ring is fixedly connected to the top of the inner support ring 51. The outer support ring 5 and the inner support ring 51 can support the support rod 42 located on the inner and outer sides respectively, thereby supporting the annular support plate 4.

[0025] Among them, a number of connecting rods 52 are fixedly connected between the outer support ring 5 and the inner support ring 51, and the connecting rods 52 are staggered with the raw material feeding hopper 1; by setting the connecting rods 52, the outer support ring 5 and the inner support ring 51 can be connected, and the inner support ring 51 can be supported by the outer support ring 5.

[0026] Among them, the bottom end of the outer support ring 5 is fixedly connected to the support leg 53; by setting the support leg 53, the device can be lifted, raising the height of the raw material feeding bucket 1.

[0027] The inner wall of the inner support ring 51 is fixedly connected to the mounting plate 54; the mounting plate 54 can serve as a support structure for installing the mixing mechanism.

[0028] Among them, the outer support ring 5 is fixedly connected to the side wall of the controller 6; the controller 6 is electrically connected to the control device of the small-volume quantitative feeding mechanism 2 and the ring weigher 3, and the controller 6 controls the small-volume quantitative feeding mechanism 2 to quantitatively replenish the material into the raw material feeding hopper 1 according to the weighing quantity of the ring weigher 3.

[0029] The working principle and usage process of this utility model are as follows: The outer support ring 5 and the inner support ring 51 are installed above the mixing tank. Multiple raw material feeding hoppers 1 are evenly distributed above the mixing tank. Multiple small-volume quantitative feeding mechanisms 2 are installed above the multiple raw material feeding hoppers 1. When adding materials, the raw materials are added until they approach the required weight. The weighing result of the ring weighing device 3 is observed. When the added weight is close to the required weight, the coarse addition is stopped. The controller 6 controls the small-volume quantitative feeding mechanism 2 to add a small amount of raw materials to the raw material feeding hopper 1 according to the difference between the measured value of the ring weighing device 3 and the actual requirement, until the weight of the raw materials in the raw material feeding hopper 1 is the same as the actual requirement. Multiple materials are added to the raw material feeding hopper 1 respectively. Multiple materials can be added at the same time or in sequence.
